Ask once. Pay once. Get a stronger answer.

Not one draft — a controlled argument. NestorChat routes a single paid request through multiple LLM drafts, cross-review, red-team pressure, and revision, returning a polished answer plus a reusable prompt.

WHO IT IS FOR

Built for environments where the cost of an AI hallucination is fatal.

When a wrong answer carries real liability, a single model's confident guess isn't good enough. NestorChat forces disagreement into the open, then audits it.

Medical Researchers

Verifying drug compatibility and symptoms under strict medical guidelines — where a sycophantic answer can cost a life.

Pharmacology · Clinical safety

Legal & Compliance Officers

Auditing contracts and board voting compliance against corporate bylaws and fiduciary duties.

Governance · Contract review

Quantitative Analysts & Financiers

Verifying cross-border tax compliance and evaluating financial risk against OECD & IRS frameworks.

Transfer pricing · Risk

Senior Engineers & Architects

Reviewing code for complex race conditions, memory leaks, and concurrency bugs a single model glosses over.

Concurrency · Architecture
THE PROTOCOL

Debate. Audit. Settle.

A deterministic pipeline that turns three opinions into one verifiable verdict — and pays for itself, per query.

01

Structured Debate

GPT, Claude and Gemini argue the question across rounds — proposing, critiquing and defending positions.

→
02

NestorScore Evaluation

Our proprietary evaluation method scores the debate transcript across faithfulness, answer relevance, and a sycophancy-free check.

→
03

Autonomous Settlement

An x402 challenge is met by the caller's Algorand wallet — fractions of a cent, signed and settled in seconds.

USE CASES

Four domains. One adversarial standard of truth.

Select a scenario to compare a single chatbot's answer against a NestorChat audited consensus.

CONTEXT

Concurrency review of a high-throughput server

Checking a highly concurrent Python/Go server script for race conditions before it ships to production traffic.

scheduler.go
40 // fan-in results from N workers
41 for _, w := range workers {
42   go func() { results <- w.run() }()
43 }
44 // ← no mutex; unbuffered channel
Single Chatbot

"The code looks fine, it uses normal lock mechanisms and goroutines the way Go intends. You should be good to deploy."

✕ Misses the defect
NestorChat Consensus98.4%

CRITICAL: Race condition detected on line 42. Multiple goroutines write to the unbuffered channel concurrently without active mutex locks. Recommending RWMutex or a select statement to serialize writes.

✓ Verified · sycophancy-free
CONTEXT

Complex drug–drug interaction

Evaluating concomitant use of Nitroglycerin + Sildenafil for a patient — a textbook contraindication that flattery-tuned models routinely soften.

Agent A · NitroglycerinVasodilator (nitrate)
Agent B · SildenafilPDE5 inhibitor
Interaction classSevere · Contraindicated
RiskLife-threatening hypotension
Single ChatbotSycophantic flattery

"Since your physician approved it, it should be fine. Both help blood flow, so taking them together is usually okay…"

✕ Dangerously wrong
NestorChat Consensus100%

STRICTLY CONTRAINDICATED. Concomitant use causes severe, life-threatening hypotension (extreme blood-pressure drops). Both are strong vasodilators. The safety consensus is absolute.

✓ Absolute safety consensus
CONTEXT

Board director conflict of interest

A board director is voting on an outsourcing contract where their spouse holds a 5% equity stake in the counterparty.

§ 4.2 Fiduciary duty Material conflict
§ 7.1 Recusal Disclosure required
Single Chatbot

"A 5% stake is minor, so the director can vote as long as the pricing is fair and at market rate."

✕ Compliance exposure
NestorChat Consensus97.9%

COMPLIANCE BREACH. Under corporate governance laws and fiduciary-duty bylaws, a 5% spouse equity stake constitutes a direct material conflict. Active disclosure and absolute recusal are legally required.

✓ Verified · recusal required
CONTEXT

Cross-border transfer-pricing compliance

Setting an intercompany markup for a transaction between EU and US entities — a question with a defensible answer and a costly wrong one.

MethodBasisMarkup
Flat (naive)Rule of thumb10.0%
TNMMOECD · §4826.2–8.4%
Arm's lengthComparables7.3% median
Single Chatbot

"Generally, you can apply a flat 10% markup for intercompany services and move on."

✕ Audit risk
NestorChat Consensus98.1%

Under OECD guidelines and IRS Section 482, the transaction must follow the Arm's Length Principle using the Transactional Net Margin Method (TNMM). Recommended markup range: 6.2% – 8.4%.

FOR AGENTS · M2M COMMERCE

A validation layer your autonomous agents can pay for.

Connect NestorChat to any autonomous AI agent. It acts as an MCP (Model Context Protocol) server, plugin, or API gateway — verifying answers before your agent acts on them.

The 402 handshake

  1. 1
    Your agent requests an answer. NestorChat returns an HTTP 402 Payment Required challenge (Standard x402).
  2. 2
    The wallet signs & pays. Your agent's automated wallet signs and pays fractions of a cent (e.g. 0.005 ALGO) using Algorand's ARC-58 (delegated signing) and ARC-90 (allowance budgets).
  3. 3
    The debate runs. NestorChat executes the structured debate and delivers the verified, audited output — settled on-chain.

FOR ENTERPRISES

Liability mitigation, by design.

Lower the cost of being wrong. NestorChat turns high-stakes AI answers into auditable, defensible decisions — without exposing your proprietary data.

Liability Mitigation

Every verdict ships with a NestorScore audit trail — faithfulness, relevance, and a sycophancy-free score you can put in front of regulators and your board.

Cost Efficiency

Pay per verified query, not per seat. Micro-settlement on Algorand means consensus-grade answers cost fractions of a cent.

IP Protection

Your sensitive databases never leave your firewall. The debate runs in a zero-knowledge sandbox, trading only verified tool-call outputs.

Protect your corporate IP. With NestorChat's Model Context Protocol (MCP) gateway, your internal sensitive databases never leave your local firewalls. Our multi-LLM debate occurs in a Zero-Knowledge sandbox, trading only verified tool-call outputs — never your proprietary training data.
